So far all the models we've seen support the HDR10 high dynamic range format, but it's possible we'll see models that also suport another type of HDR, Dolby Vision, in the future.
In addition to playing 4K Ultra HD Blu-ray discs, all Ultra Blu-ray players will also up-convert standard HD Blu-rays to quasi-4K resolution, something the TV can also do.
Some models include a feature called 4K upscaling, which means the player will take 1080i and 1080p content and upconvet it to quasi-4K resolution when used with a 4K UHD TV.
(All UHD TVs will also perform this up-conversion, so it’s not an essential feature, but the Blu-ray player may do a better job.) However, there are now 4K Ultra HD Blu-ray players that can present true 4K images with 4K TVs.
Some models may support other types of specialized discs, such as audiophile SACDs.
If you have an HDTV, we strongly recommend that you buy a Blu-ray player rather than a standard DVD player.
Many players include USB port and/or a memory-card slot, which allow you to play digital media files, such as music, photos, or videos, on your TV.Most have built-in Wi Fi for connecting to your network.Some models still offer 3D capability if that is still of interest to you.You can still find 3D-capable Blu-ray players, though that feature is now being included on fewer TVs.When used with 3D discs, 3D glasses, and a 3D TV, they enable you to see three-dimensional images.
